“…It is seen that bismuth (III) reduction is a single-step, three-electron-transfer process with a peak potential of  82 mV ( Fig. 1a), [29][30][31] whereas tin (IV) reduction is a two-step process, with a sharp peak at -202 mV and an increasing current starting from -502 mV (Fig. 1b), with the latter corresponding to Sn 4+ reduction to Sn 2+ , and the former to the reduction of Sn 2+ ions.…”

Electrodeposition of tin-bismuth alloys on polycrystalline copper electrodes has been studied from an acidic bath comprising SnCl4, Bi(NO3)3, citric acid, poly(vinyl alcohol) and betaine. Using linear sweep voltammetry (LSV) and chronoamperometry (CA), co-deposition of tin and bismuth from the above bath has been examined. Bismuth (III) ions get reduced in a single-step, three-electron-transfer reaction while tin (IV) ions undergo a two-step reduction through the formation of tin (II) ions. Nitric acid in the bath not only enhances solubility of the precursors but also decreases the peak potential separation between bismuth (III) and tin (II) ions. Through the introduction of various additives and variation in bath pH, co-deposition is preserved while the composition of tin in the obtained alloy is modified. The morphologies, composition and crystallinity of the deposits have been determined using scanning electron microscopy, inductively coupled plasma atomic emission spectroscopy and X-ray diffraction, respectively. A wide range of alloy compositions (from 14% to 75% tin), including the eutectic Sn-Bi alloy have been deposited. Novel morphologies such as yarns-of-spool have been obtained.

“…The charging-discharging voltage profiles and cyclability are shown in Figure 6c,d. [21] The reactions of MnO 2 -Zn and MnO 2 -Bi batteries are elaborated in Note S5 of the Supporting Information. Apart from the incomplete dissolution of MnO 2 in the discharging cycle, the low CE can be ascribed to the quasi-reversible plating and stripping process of Bi metal.…”

cations), [1] as well as novel electrolytes with broadened electrochemical stability window such as the water-in-salt electrolytes. [2] Comprehending battery chemistries enlightened to battery performance improvement, which could be classified into two typical charge storage mechanisms for electrode materials, namely, insertion/extraction mechanism and chemical conversion mechanism. Thus, as for a full aqueous battery, three dominated working principles can be identified based on the reactions occurred in electrode materials. Specifically, the first is the rocking-chair type that both cathode and anode materials provide intercalation channels for ions, such as alkaline cation batteries. [1a,2a,3] The second is a mixed process, such as newly reported Zn 0.25 V 2 O 5 -Zn and LiMn 2 O 4 -Zn batteries, in which ions intercalation happens in cathode (Zn 2+ inserted into Zn 0.25 V 2 O 5 , Li + into LiMn 2 O 4 ) and the conversion reaction dominates in the counterpart anode (plating-stripping of Zn). [1c,d,2b] However, the third working principle, of which chemical conversion reactions proceed in both cathode and anode materials for aqueous batteries, has been scarcely explored, only including traditional leadacid batteries [4] and sporadic examples. [1b,5] Nevertheless, it is inspiring that the battery performance based on chemical conversion mechanism exhibits outstanding performance, such as high voltage, large capacity, and stable cyclability. [1b,4a,5,6] Thus, adopting conversion mechanism on both electrodes may open a new door to improve aqueous battery performance and it is of large potential to broaden the selection spectrum of electrode materials and electrolytes. However, to our knowledge, there is no systematic methodology to design batteries based on conversion reactions for both electrodes and the corresponding chemistry is far from being well understood.Electrodeposition is a powerful and versatile theme in electrochemistry, which enables diversified applications, such as materials synthesis and anticorrosive coating, by in situ synthesis of insoluble deposits at solid-liquid heterogeneous interfaces. [7] The deposition reactions can be triggered on specific conditions, kinetically and thermodynamically, including externally applied potentials, pH, temperature, and ion concentration variations. Various species, such as metals or metal Conventional charge storage mechanisms for electrode materials are common in widely exploited insertion/extraction processes, while some sporadic examples of chemical conversion mechanisms exist. It is perceived to be of huge potential, but it is quite challenging to develop new battery chemistry to promote battery performance. Here, an initiating and holistic deposition-dissolution battery mechanism for both cathodes and anodes is reported. A MnO 2 -Cu battery based on this mechanism demonstrates outstanding energy density (27.7 mWh cm −2 ), power density (1232 mW cm −2 ), high reversibility, and unusual Coulombic efficiency. It can be charged to 0.8 mAh cm −2 within 42...

“…However, the metal ions in the horizontal space between the growing deposits deplete rapidly and cannot be replenished in time, which prevents further nucleation and growth there. [15] The preferential nucleation and the growth modulation finally lead to the formation of Sb prisms. The deposited samples were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).…”

Antimony (Sb) is a promising anode material for sodium‐ion batteries owing to its large capacity of 660 mAh g−1. However, its practical application is restricted by the rapid capacity decay resulted from a large volume expansion up to 390% upon Na alloying. Herein, construction of a self‐supported Sb array that has enough space allowing for effective accommodation of the volume change is reported. The array of Sb prisms is directly grown on a Cu substrate via a template‐free electrodeposition, followed by mild heating to consolidate the structural integrity between Sb and Cu. The resulting 3D architecture endows the Sb array with excellent sodium storage performance, exhibiting a reversible capacity of 578 mAh g−1 and retaining 531 mAh g−1 over 100 cycles at 0.5 C. The potential of Sb array in sodium‐ion full cells by pairing it with a Na0.67(Ni0.23Mg0.1Mn0.67)O2 cathode is further demonstrated. This full cell affords a specific energy of 197 Wh kg−1 at 0.2 C and a specific power of 1280 W kg−1 at 5 C. Considering its low cost and scale‐up capability, the template‐free route may find extensive applications in designing electrode architectures.
